This invention relates to firearms and has for an object an improved target rifle of the sliding action rod type.

In a rifle embodying the invention, the receiver comprises a barrel portion and a stock portion which are interconnected in a manner permitting them easily to be separated for taking down the gun. The barrel portion is provided with a pair of side plates fitting 1 within the side walls of the stock portion. The carrier is pivotally mounted between said plates and the breech bolt assembly is slidably mounted therebetween. The trigger and hammer are pivotally mounted on the stock portion of the receiver and one side wall of the stock portion is detachable to uncover the correspondin side plate of the barrel portion and also the trigger and hammer. A springpressed plunger is provided in the stock and between it and the hammer there is provided a rod, the ends of which seat in recesses, one in the plunger and the other in the hammer. This rod may easily be removed from between the plunger and the hammer without removal of either from the rifle. By having one wall of the stock portion removable to uncover the hammer and trigger, it is possible easily to remove these elements to make slight changes therein when adjusting the trigger pull be- FO fore final assembly of the gun.

Other objects, novel features and advantages of this invention will be apparent from the following specification and accompanying drawings, wherein:

The rifle comprises a standard stock 10 and a barrel 11 connected by means of a twopart receiver 12. The magazine 13 is supported beneath the barrel 11 and communicates with the receiver 12. An action rod handie 14: is slidably supported by the magazine 13 and is connected to an action rod 15 which extendsinto the receiver through the front wall thereof. A portion 12 of the receiver'is carried by the barrel and is provided with side walls 16. A spacing pin 16 is arranged between the side walls 16 and maintains said walls properly spaced. The remainingportion 12 of the receiver is carried by the stock 12 "and is provided with an integral side wall 05 17 and a detachable side plate 17 a which overlie the walls 16 and engage the portion 12.

The portion 12 is provided with recesses 18 within which are received prongs 19 provided on the stock portion 12 The barrel portion 12 and stock portion 12 are provided near their front ends with co-acting oblique surfaces 20 and 20*, the contacting of which is effective to draw the prongs 19 into the recesses 18. The two parts 12 and 12" are assembled by inserting the prongs '19 into the recesses 18 with the barrel portion and stock portion angularly related and then swinging the same to bring the co-acting surfaces 20 and 20 into contact. The barrel 8C portion 12" is provided with an oblique slot 21 which receives a bolt 22 carried by'the walls of the stock portion 12 One end of this bolt lies substantially flush with the side wall 17 and is fixed thereto, while theother end projects through a hole in the removable side plate 17*. A nut 23 is threaded on the projecting end of the bolt 22 and has a portion 24 of reduced diameter adapted topass through the hole in the side plate 17 and into a countersunk recess at the end ofthe slot 21. This nut, when the portion 24 is engaged in the countersunk recess, effectively prevents relative angular movement of the stock and barrel portions, thereby holding the same in assembled relation.

The breech bolt 25 is operated in the wellknown manner by the action rod '15'to which it is connected. The action rod 15 lies in a slot 26 in a side wall-l6 and is provided with a lug 27 which projects into a slot 28 provided for it in the breech bolt. The carrier 29 is pivotally supported between the walls 16 by a pin 80. A. hammer 31 is rotatably mounted on a stud 82 supported by a wall of the stock portion 12 and a trigger 33 is pivotally supported by the stock portion and cooperates with the hammer in the usual manner. The receiver is provided wita a tang portion which comprises a tubular member 34 provided with a head 35 having a tapering por tion which is received within a corresponding recess formed partly in the rear wall of the stock portion and partly in the removable side plate 17. A bolt 36 is provided in the rear Wall of the stock and is threaded into the head 35 and a bolt 36 passes through the side plate and is also threaded into the head 35.

The tubular member extends rearwardly from the stock portion and in it is provided the hammer actuating spring 37, the front end of which engages aplunger 38 slidably mounted in the tubular member. The front end of the plunger 88 is recessed and receives one end of a rod 39, the other end of which is received within a vertical recess 40 in the hammer 31. Near the rear end of the stock 10 there is provided a bushing 41 through.

wvhich extends a bolt 42 which is threaded into the rear end of the tubular member 34;. The stock portion 12 is provided around the tubular member 3a with a recess into which projects the nose of the stock 10. The stock 10 is held to the stock portion 12 through the medium of a bolt l2 and tubular member 34. The side plates 17 may be removed by taking out the bolt 36 and screwing off the nut 23 which is replaced aft r the plate has been removed. The side plate 17 when removed, uncovers the corresponding side wall 16 and also the hammer and trigger which may be removed while the remaining parts are retained in assembled relation. In order to take out the hammer with the side wall removed, the hammer is moved into cocked position, thus forcing the plunger 88 into the tubular member 37. A. suitable tool is then inserted through the hole for the bolt 36 to retain the plunger within the tubular member. The hammer is then returned to firing position whereupon the bar 39 may be easily lifted out after which the hammer may be slid off the stud 32. This feature is v ery helpful in connection with making the final adjustments on the hammer and trigger for obtaining the proper pull on the trigger and also for making other changes incidental to the final adjustment of the gun.

It is of course understood that various modifications may be made in the structure above described, without in any way departing from the spirit of the invention as de fined in the appended claims.
